Von Duyke, Wilmington, Del., assignor to New Dictatype Company, Incorporated, Wilmington, Del., a corporation of Delaware Application November 5, 1947, Serial No. 784,254 7 Claims. (01. 197 1ss This invention relates to paper supply and receiving trays for stenographic typewriters, and it relates more particularly to an improved form of device adapted to hold a supply of fan folded paper in strip form, so constructed and arranged as to cause the paper strip, after the same has passed over the platen of the typewriter, to be refolded and deposited on an upper shelf of the device.

The principal object of the present invention is to provide an improved form of tray for holding a supply of fan-folded paper, and for receiving the same on an upper shelf thereof after the paper passes over the platen of the typewriter. I

A further object of the invention is to provide a device of the character aforesaid, which may be positioned under the operating parts of the typewriter when the same is not in use, but which may be quickly and easily brought to operative position when required.

A further object of the invention is to provide a device of the character aforesaid, which is so constructed and arranged as to insure the proper refolding of the paper after the same has passed over the platen.

The nature and characteristic features the present invention will be more readily understood from the following description, taken in connection with the accompanying drawing forming part hereof, in which:

Figure .1 is a perspective View of a paper tray embodying the main features of the present invention, the same being shown in a distended or operative position, but without any paper shown therein;

Fig. 2 is a longitudinal sectional view of the tray illustrating the same in operative relationship with the platen of a typewriter;

Fig. 3 is a transverse section taken approximately on the line 3--3 of Fig. 1;

Fig. 4 is a similar view, the section being take approximately on the line 4-4 of Fig. 1'; and

Fig. 5 is a fragmentary perspective view, partly in section taken on the line 5-5 of Fig. 1.

It should, of course, be understood that the description and drawing herein are illustrative merely, and that various modifications and changes may be made in the structure disclosed "without departing from the spirit of the invention.

Referring to the drawing, in the particular embodiment of the invention therein shown, It is a base tray having a bottom or floor portion .11! in which a plurality of holes l2 are located.

The holes I2 not only serve to eliminate the collection of dirt'in the tray, but also to assist in removing any portions of the paper pad which may be left in the tray, or which it may be necessary to remove therefrom.

The base tray 10 is provided with side walls l3 and a wall 14, at the front end, which is relatively low, there being no necessity for a high wall at both ends of the tray. The rear end of the tray is provided with a higher wall 15.

The side walls 13 are each provided with wings it which are slidably mounted in grooves l1 provided in the side rails l8 on each side of the device.

The side rails l 8 are also provided with grooves 20 which are engaged by suitable lugs 2| .and 22 provided by bending suitable portions of the base plate 2.3 of the typewriter machine.

The base plate 23 is also provided with lugs 24, which extend into the grooves ll of the side rails l8 and serve, in coniunction with the downwardly bent portions 25 at the forward ends of the rails It, as stops to limit the rearward-extension of the tray and its associated parts.

Also, at the rear end of each rail [8, the metal is bent downwardly and over the ends of the grooves 18, as at 4|, to serve as .a stop for limiting the outward extension of the tray beyond its proper operative location. The stop may be readily obtained by the termination of the wings 16 at the proper locations, but it is preferred to shape the metal of the side walls l3 of the base tray so that the lug-like portions 40 thereof extend around on the outside of the vertical portion of theside rails, and in this mannerthe parts will be held together without likelihood of disengagement through rough handling of the device. Q

The shelf for receiving the paper, after it has passed over the platen 39 of the typewriter machine, comprises a plate 3| having relatively low side walls 32. Each of the side walls 32 has apin extending sidewise near the rear end thereof. The pins 33 extend through slots 34 in the side walls l3 of the base tray ill. The slots 34 are shaped to provide offsets 35 near the top so that when the shelf Si is brought to the proper operative position, the pins 33 will be seated in the Ohsets 35.

The shelf 30 is also provided at its rear end with an upwardly projecting portion 35 which is adapted to extend into a slot provided by means of a portion 31 of the rear wall l5 of the base tray It! being bent inwardly as shown in Figs. 1 and 2 of the drawing.

The foregoing arrangement is such that not only will the shelf 3| be held in the proper position by the coaction of the pins 33 with the slots 34, as well as the coaction of the portion 36 with rest in the base tray I 0, and the base tray as well 7 as the slides l8 will have been pushed under the operating parts of the typewriter.

Whenever it is desired to use the typewriter machine, the base tray II) will first be pulled rearwardly to the fullest extent, the final position being limited by stops 24 and 25 at the front ends of said rails l8, and the stops 4B and 4| at the rear ends of said rails.

The shelf 3| is now manually brought to the proper operative position with the pins 33 seated in the offsets 35 of the slots 34, and the upwardly extending portion 36 at the rear of shelf 3| is brought into engagement with the bent-in portion 37 of the rear wall I 5 of the base tray [9.

The end of the paper is then fed around the platen 30 in the usual manner, after which the front end of the paper is gripped between the parts 36 and 31, the front end of the shelf being raised slightly so that there will be sufficient space to permit the insertion of the end of the paper between the bent-up portion 35 of shelf 3| and thebent-in portion 31 of the rear wall I5. The paper having been so inserted. the front end of the shelf 3| is lowered to operative position, and

the paper will then be firmly gripped between the said parts 36 of shelf 3| and 31 of wall l5.

From then on the operation is automatic, and

as the paper is fed around the platen from the refolding to occur at the front end of the shelf 3| The device has been found in practice to operate satisfactorily and much better than the devices heretofore available for a similar purpose.
